1. Molecular and Genetic Evidence for Antigen Selection in the Pathogenesis of Chronic Lymphocytic Leukemia
Abstract : Antigens play a critical role in the development of chronic lymphocytic leukemia (CLL) by binding to and stimulating leukemic precursor cells at some point during CLL ontogeny. Nevertheless, much remains unknown and further studies are necessary before an accurate model of antigen-drive can be ascertained. READ MORE

2. Molecular Interrogation and Functional Studies of Acute Leukemia
Abstract : Hematological malignancies are defined by their underlying genetic alterations, many of which are used to diagnose patients to classify them to different risk groups that dictate the therapy given. Recent advances in high-throughput sequencing have highlighted the presence of co-occurring genetic lesions and that they may form distinct genetic clones that evolve throughout disease progression.

3. Hematopoietic stem cells: c-mpl and TNF receptor function
Abstract : Hematopoietic stem cells (HSC) are crucial to life. Daily and throughout the life span of an individual they are responsible for replacing approximately 10(12) mature blood cells. Mature cells are, for example, required for transportation of oxygen, defense against infections and to stop bleeding. READ MORE

4. Studies of T cells in health and disease : receptor usage and cytokine expression
Abstract : T Iymphocytes are crucial components for the initiation and maintenance of an immune response. To identify and characterize different T cells and their antigen specific receptors has important bearing for the understanding of underlying mechanisms in immunopathological processes and also to allow for the design of therapeutic therapies to be used for modulation of immune responses.

5. T cell antigen receptor usage, phenotype and cytokine production in human diseases
Abstract : T lymphocytes are of critical importance for initiating and controlling immune responses, as the T cell receptor (TCR) for antigen allows a highly specific antigen recognition. Determination of TCR usage and characterization of T cell subsets in different diseases helps us understand the underlying immunopathogenic mechanisms, and may also lead to the development of new therapeutic approaches.
